Review on Sound toothbrush Philips Sonicare DiamondClean Smart HX9924/07, white by Ngo Quang Cuong  (Cn ᠌

The brush excels in every conceivable respect. When you take into account all of the features that come standard with this brush, it is easy to see why it retails for such a high price. Brushing your teeth on a consistent basis is going to save you far more time and money in the long run compared to getting your teeth treated and whitened professionally. Everything is fairly straightforward; all we need to do is read the instructions, choose the appropriate nozzle and mode for the task at hand, synchronize the brush with the program running on our smartphone, and then follow the instructions. The first time I tried to synchronize the application with the brush, it did not work for me. However, everything turned out well in the end, and those support helped me a lot with this. I would like to bring it to the attention of those people who do not read the instructions that the brush operates a little bit differently when it is not synchronized with the application as opposed to when it is synchronized with the application. Brush heads, a tongue cleaner, and a teeth whitening brush are included in the package with the toothbrush. Glass and a transportable case (wireless charging) Once you've finished cleaning the brush, place it in the glass, and you'll never have to worry about charging it again. Because a modern battery is utilized in the toothbrush, which is also utilized in Tesla automobiles, smartphones, and laptops, this indicates that you will have sufficient charge for an extended period of time and, if necessary, the toothbrush can be recharged at any time that is convenient; this is made possible by a modern battery. In case you were wondering, the carrying case not only serves the purpose of transporting the brush from one luggage to another, but it also has the role of charging the brush. The USB cable that comes with the cover can be used with any USB charger that comes with a smartphone or tablet.
